Abstract
A glass plate storage jig (1) stores a plurality of glass plates (2) in a state of being arranged at intervals in a thickness direction in a standing posture so as to be immersed in a chemical strengthening liquid. The glass plate storage jig (1) is provided with a string-like body (7) made of at least one metal fiber. The end part (2a) of the glass plate (2) is supported by a V-shaped concave part (7c) formed by the intersection of a pair of rope-shaped bodies (7a, 7 b).
Description
Technical Field
The present invention relates to a glass plate storage jig and a technique for improving a method for manufacturing a chemically strengthened glass plate, in which a plurality of glass plates are stored in a state of being arranged at intervals in a thickness direction in an upright posture so as to be immersed in a chemical strengthening liquid.
Background
As a method for improving the mechanical strength of a glass sheet, a method called chemical strengthening has been conventionally used. In this chemical strengthening, the glass sheet is immersed in a chemical strengthening solution to replace ions on the glass surface with ions in the chemical strengthening solution, thereby generating a compressive stress on the glass surface and improving the mechanical strength.
The chemical strengthening step is usually performed by preheating, strengthening, and gradually cooling in this order. In detail, the chemical strengthening step is carried out by first heating the glass plate to about 400 ℃ in the preheating step for about 1 to 2 hours at room temperature with air. Then, in the strengthening step, the glass sheet is immersed in a chemical strengthening solution at about 400 ℃ for 2 to 4 hours. And finally, in the gradual cooling process, cooling the glass plate to the normal temperature after 3-4 hours.
In the chemical strengthening step, a glass plate storage jig is used when the glass plate is impregnated with the chemical strengthening solution in the chemical strengthening tank.
In this glass plate storage jig, the glass plate swings due to vibration during conveyance of the glass plate or cooling air in the cooling step, and the glass plate and a support portion supporting the glass plate repeatedly contact each other, thereby possibly forming a notch or a scratch in the glass plate.
To avoid this, in the glass plate housing jig of patent document 1, for example, the surface of the support portion for supporting the glass plate is covered with a woven cloth made of stainless steel.

However, in the glass plate storage jig described in patent document 1, when the glass plate is pulled up from the chemical strengthening liquid, the stainless steel woven fabric contains the chemical strengthening liquid, and the chemical strengthening liquid may drip and adhere to the end portion of the glass plate, and hence there is a possibility that the glass plate is contaminated. Further, since the stainless steel woven cloth is fixed to the glass plate by the chemical strengthening liquid (strengthening salt) after curing, there is a possibility that cracks or scratches are generated in the glass plate when the stainless steel woven cloth is peeled. Further, the woven fabric containing the chemical strengthening solution and the glass plate are continuously brought into contact with each other for a long time in the gradually cooling step, thereby locally promoting ion exchange and possibly causing unevenness in chemical strengthening.

Problems to be solved by the invention
In view of the above circumstances, the present invention has an object to prevent breakage and chipping of a glass sheet and to suppress contamination of the glass sheet or occurrence of unevenness in chemical strengthening due to a chemical strengthening liquid.
Means for solving the problems
In order to solve the above-described problems, a glass plate storage jig according to the present invention is a glass plate storage jig that stores a plurality of glass plates in a state in which the glass plates are arranged at intervals in a thickness direction in an upright posture, the glass plate storage jig including a string-shaped body made of at least one metal fiber, wherein an end portion of the glass plate is supported by the string-shaped body. Here, the string-like body includes, in addition to a member formed by twisting a plurality of metal fibers into a string-like shape, a long metal fiber (wire), a member formed by bundling a plurality of metal fibers without twisting, a member formed by bonding the metal fibers in a state of being bundled without twisting, and the like, except for a member formed by forming metal fibers into a cloth-like shape such as a woven fabric or a nonwoven fabric (the same applies hereinafter).
In this structure, the end portions of the glass sheet are supported by the string-like bodies. Further, since the string-like body is not in a cloth shape, the contact area with the end portion of the glass sheet is small, and the amount of the chemical strengthening liquid contained after being pulled up from the chemical strengthening liquid is also small. Therefore, the amount of the chemical strengthening liquid dropped from the string-like body after the glass sheet is pulled up from the chemical strengthening liquid is also small, and the glass sheet can be prevented from being contaminated by dropping of the chemical strengthening liquid. Further, since the fixation of the glass plate and the string-like body by the chemical strengthening liquid (strengthening salt) after curing is also suppressed to the minimum, it is also possible to prevent the glass plate from being broken or chipped. Further, since it is possible to avoid the situation in which the end portion of the glass sheet continues to be in excessive contact with the chemical strengthening liquid after being pulled up from the chemical strengthening liquid, it is possible to suppress the occurrence of chemical strengthening unevenness.
In addition to the above configuration, it is preferable that the string-shaped body is formed by twisting a plurality of metal fibers.
According to this structure, the breaking strength of the string-like body can be improved.
In any of the above configurations, it is preferable that the end portion of the glass sheet is supported by a V-shaped recess formed by the intersection of the pair of string-like bodies.
According to this configuration, since the end portion of the glass plate is supported by the V-shaped concave portion, the movement of the glass plate can be restricted, and the glass plate can be supported more reliably.
In the above configuration, preferably, the pair of string-like bodies intersect with each other and extend in the thickness direction in a zigzag shape, and a plurality of V-shaped concave portions are formed in the thickness direction.
According to this configuration, a plurality of V-shaped recesses can be easily formed in the thickness direction of the glass plate. Further, since the pair of string-shaped bodies extend to form the plurality of V-shaped concave portions, the tension of each V-shaped concave portion can be more easily made uniform than when each V-shaped concave portion is formed in a single pair of string-shaped bodies. This makes it possible to make the supporting force of the end portion of the glass plate uniform by the V-shaped concave portions.
In the above configuration, preferably, the pair of string-like bodies are fixed to a fixing member at a vertex of the zigzag shape.
According to this configuration, the string-like body can be easily formed into a zigzag shape. Further, even if the string is broken between certain apexes, the string between other apexes can be prevented from slackening.
In any of the above configurations, it is preferable that at least an upper end portion and both side end portions of the glass plate are supported by the string-like body.
That is, without any of the above-described means, after the glass sheet is pulled up from the chemical strengthening liquid at the upper end portion and both side end portions of the glass sheet, the chemical strengthening liquid easily drops from the support portion of the glass sheet toward the glass sheet side. Therefore, according to the above configuration, it is possible to effectively suppress the chemical strengthening liquid from dripping from the glass support portion toward the glass plate side.
The method for manufacturing a chemically strengthened glass plate according to the present invention, which has been accomplished to solve the above problems, includes an immersion step in which a plurality of glass plates are immersed in a chemical strengthening liquid in a state in which the glass plates are arranged in an upright posture at intervals in a thickness direction, and is characterized in that an end portion of the glass plate is supported by a string-like body made of at least one metal fiber in the immersion step.
In this configuration, substantially the same operation and effect as those described in the above-described embodiments can be obtained.
Effects of the invention
As described above, according to the present invention, it is possible to prevent the glass sheet from being broken or chipped, and to suppress the contamination of the glass sheet or the occurrence of unevenness in chemical strengthening due to the chemical strengthening liquid.

Detailed Description
The present embodiment will be described below with reference to the drawings.
Fig. 1 is a perspective view showing a glass plate storage jig 1 according to an embodiment of the present invention. The glass plate storage jig 1 stores a plurality of glass plates 2 in a state of being arranged at intervals in a thickness direction in an upright posture so as to be immersed in a chemical strengthening liquid.
In the present embodiment, the glass plate 2 has a rectangular shape, and the size of the glass plate 2 is, for example, 1m × 1m or more, but may be smaller than this size. The thickness of the glass plate 2 is, for example, 0.05mm to 2.00mm, but not limited thereto.
For convenience of explanation, in the present embodiment, the thickness direction of the glass plate 2 in fig. 1 is defined as the front-rear direction, the near side in fig. 1 is defined as the front side, and the deep side is defined as the rear side. And, the longitudinal and lateral directions are those of the glass plate 2.
The glass plate housing jig 1 has a frame shape in the present embodiment, and surrounds a plurality of glass plates 2 arranged, thereby forming a space for housing the glass plates 2.
In the present embodiment, the glass plate housing jig 1 includes column portions 3 arranged at the corners of a rectangle in a plan view and extending in the vertical direction, a plurality of beam portions 4 extending in the front-rear direction between the column portions 3 and connecting the column portions 3, and a plurality of beam portions 5 extending in the lateral direction between the column portions 3 and connecting them.
In the present embodiment, the beam portions 5 include a pair of upper beam portions 5a that connect the vertically intermediate portions of the column portions 3 to each other, a pair of intermediate beam portions 5b disposed below the upper beam portions 5a, and a pair of lower beam portions 5c that connect the vertically lower end portions of the column portions 3 to each other. The pair of upper beam portions 5a, the pair of intermediate beam portions 5b, and the pair of lower beam portions 5c are disposed at the same height in the front and rear of the glass sheet storing jig 1.
The glass plate storage jig 1 further includes a support portion for supporting the glass plate 2. The support portions include a pair of upper support portions 6a that support the upper end portion of the glass plate 2 from above, two pairs of side support portions 6b that support the side end portions on both sides of the glass plate 2 from the sides, and a pair of lower support portions 6c that support the lower end portion of the glass plate 2 from below. The number of the upper support portions 6a and the side support portions 6b is not particularly limited, and may be appropriately changed according to the size of the glass plate 2 or the like.
Both ends of the upper support portion 6a in the front-rear direction are detachably attached to the upper surfaces of the pair of upper cross members 5a by fastening members such as bolts, not shown.
Both ends in the front-rear direction of the pair of side support portions 6b of the two pairs of side support portions 6b are fixed to the upper surfaces of the pair of upper cross members 5a by fastening members such as bolts, not shown. Both ends in the front-rear direction of the remaining pair of side support portions 6b of the two pairs of side support portions 6b are fixed to the upper surfaces of the pair of intermediate cross member portions 5b by fastening members such as bolts, not shown.
Both ends of the lower support portion 6c in the front-rear direction are fixed to the upper surfaces of the pair of lower cross members 5c by fastening members such as bolts, not shown.
As shown in fig. 2, the main components of the upper support portion 6a and the side support portion 6b include a string-like body 7 that supports the end portion 2a of the glass plate 2, and a fixing member 8 that fixes the string-like body 7. The fixing member 8 has V-shaped groove portions 8a formed at predetermined intervals in the front-rear direction.
On the other hand, although not shown, in the present embodiment, the lower support portion 6c includes a flat plate-like member and a metal woven fabric fixed to the flat plate-like member. The lower support portion 6c supports the end portion 2a of the glass plate 2 with the woven metal cloth. The metal woven fabric is fixed to the flat plate-like member by being wound around the string-like body 7 in a state of being placed on the flat plate-like member, for example.
In the present embodiment, the string-like body 7 is configured by twisting a plurality of metal fibers. The diameter of the string-like body 7 is, for example, preferably 0.2mm to 1.0mm, more preferably 0.3mm to 0.9mm, and most preferably 0.4mm to 0.8 mm. When the diameter of the string-like body 7 is less than 0.2mm, the strength of the string-like body 7 may be insufficient. When the diameter of the string-like body 7 is larger than 1.0mm, the flexibility may be insufficient.
The diameter of the metal fibers constituting the string-like body 7 is, for example, preferably 8 to 16 μm, more preferably 9 to 15 μm, and most preferably 10 to 14 μm. In the case where the diameter of the metal fiber is less than 8 μm, there is a possibility that the strength is insufficient. When the diameter of the metal fiber is larger than 16 μm, the flexibility may be insufficient.
The material of the metal fibers constituting the string-like body 7 is not particularly limited as long as it is excellent in heat resistance, has corrosion resistance against the chemical strengthening liquid, and does not elute impurities, and examples of such a material include stainless steel such as SUS304 and SUS 316. The same applies to the metal fibers of the metal woven fabric constituting the lower support portion 6 c. The materials of the portions of the glass plate storage jig 1 other than the string-like body 7 and the metal woven cloth are the same.
In the present embodiment, each of the pair of string- like bodies 7a and 7b has a zigzag shape and extends in the front-rear direction. The pair of string- like bodies 7a and 7b intersect each other at a plurality of positions in the front-rear direction. The pair of string- like bodies 7a and 7b are fixed to the fixing member 8 at the apexes of the zigzag shape by fastening members such as bolts 8b and washers. In the present embodiment, the pair of string- like bodies 7a, 7b are connected at one end thereof and formed as a part of one long string-like body 7.
In the present embodiment, the zigzag shape of the string-like bodies 7a has a constant bending angle and a constant size of the straight line portion, and the zigzag shape of the string-like bodies 7b has a constant bending angle and a constant size of the straight line portion. The zigzag-shaped curved angle of the string-shaped body 7a is the same as the zigzag-shaped curved angle of the string-shaped body 7b, and the zigzag-shaped straight line portion of the string-shaped body 7a has the same size as the zigzag-shaped straight line portion of the string-shaped body 7 b.
The string- like bodies 7a and 7b are arranged such that the widthwise center lines (straight lines in the front-rear direction) of the respective zigzag shapes overlap. The string- like bodies 7a and 7b are arranged in such a manner that the respective zigzag shapes are symmetrical about the center line of the overlap.
The end 2a of the glass plate 2 is supported by a V-shaped recess 7c formed in the peripheral portion of the intersection between the pair of string- like bodies 7a and 7 b. In the present embodiment, the pair of string- like bodies 7a and 7b contact each other at the intersecting position, but may not contact each other as long as the end 2a of the glass plate 2 can be supported by the V-shaped recess 7 c. In the illustrated example, the end 2a of the glass plate 2 is rounded, but the present invention is not limited thereto, and may be, for example, angular or chamfered.
The angle α of the V-shaped recess 7c is preferably 120 ° or less, and more preferably 90 ° or less. If the angle α is greater than 120 °, the movement of the end portion 2a of the glass plate 2 cannot be restricted, and the end portion 2a of the glass plate 2 may not be supported reliably. The angle α of the V-shaped recess 7c is set larger than the angle β of the V of the groove 8 a.
In the present embodiment, the V-shaped recess 7c is located at the same position as the groove 8a of the fixing member 8 in the front-rear direction. As shown in the illustrated example, in a state where the end portion 2a of the glass plate 2 is supported by the V-shaped recess 7c, there is a gap between the end portion 2a of the glass plate 2 and the groove portion 8a, and even if the glass plate 2 moves slightly in the front-rear direction due to slight vibration or the like, the end portion 2a of the glass plate 2 does not come into contact with the groove portion 8a, and the end portion 2a of the glass plate 2 is not damaged. On the other hand, when the glass plate 2 is intended to be moved largely in the front-rear direction due to large vibration or the like, or when the string-like bodies 7 are broken, the groove portions 8a of the fixing members 8 regulate the front-rear direction position of the end portions 2a of the glass plate 2, and the adjacent glass plate 2 can be prevented from coming into contact with.
Next, a method for producing a chemically strengthened glass plate according to an embodiment of the present invention will be described.
In the present embodiment, the method for producing a chemically strengthened glass plate includes a preheating step, a strengthening step (immersion step), and a cooling step.
First, at normal temperature, in the glass plate storage jig 1 with the upper support portion 6a removed, the plurality of glass plates 2 are arranged in an upright posture with a gap in the thickness direction, and then the upper support portion 6a is attached to the glass plate storage jig 1. Thereby, the upper end portion and both side end portions of the glass plate 2 are supported by the string-like bodies 7.
Then, in the preheating step, the glass plate housing jig 1 housing the glass plate 2 is air-heated to about 400 ℃ over about 1 to 2 hours, and the glass plate 2 at room temperature is heated to about 400 ℃.
After the preheating step, in the strengthening step, the glass plate holding jig 1 holding the glass plate 2 is immersed in a chemical strengthening solution at about 400 ℃ for 2 to 4 hours to chemically strengthen the glass plate 2.
After the strengthening step (after being pulled up from the chemical strengthening liquid), in the gradual cooling step, the glass plate in the glass plate housing jig 1 housing the glass plate 2 is cooled to room temperature over 3 to 4 hours, and the glass plate 2 is cooled to room temperature.
After the cooling step, the upper support portion 6a is removed from the glass plate housing jig 1 at normal temperature, and the glass plate 2 is taken out from the glass plate housing jig 1. Thus, the chemically strengthened glass plate 2 is obtained, and the method for producing a chemically strengthened glass plate according to the present embodiment is completed.
In the glass plate storage jig 1 configured as described above, the end portion 2a of the glass plate 2 is supported by the string-like body 7. The string-like body 7 has a small contact area with the end 2a of the glass plate 2, and contains a small amount of the chemical strengthening liquid after being pulled up from the chemical strengthening liquid. Therefore, the amount of the chemical reinforcing liquid dropped from the string-like bodies 7 after the glass sheet 2 is pulled up from the chemical reinforcing liquid is also small, and contamination of the glass sheet 2 due to dropping of the chemical reinforcing liquid can be suppressed. Further, since the fixation of the glass plate 2 and the string-like bodies 7 by the chemical strengthening liquid (strengthening salt) after curing is also suppressed to the minimum, it is also possible to prevent the glass plate 2 from being broken or chipped. Further, since it is possible to avoid the end portion 2a of the glass plate 2 from being in excessive contact with the chemical strengthening liquid after being pulled up from the chemical strengthening liquid, it is possible to suppress the occurrence of chemical strengthening unevenness. The string-like body 7 is made of metal fibers, and therefore has predetermined flexibility. Therefore, even if the glass plate 2 repeatedly comes into contact with the string-like bodies 7, the glass plate 2 is less likely to be chipped or scratched. As described above, according to the glass plate housing jig 1 of the present embodiment, it is possible to prevent the glass plate 2 from being broken or chipped, and to suppress the contamination of the glass plate 2 by the chemical strengthening liquid and the occurrence of unevenness in chemical strengthening.
The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea thereof. For example, in the above embodiment, the lower support portion 6c is made of metal woven cloth and supports the lower end portion of the glass plate 2, but the lower support portion 6c may also support the lower end portion of the glass plate 2 by the string-like body 7.
